To @ZZ 207mmy it 77mg/ concern.'

Be it known that I, WALTER G. lNrLkns, a citizen oit the United States of America, and a resident ot Biloxi, in the county of Harrison and State. of Mississippi, have invented a new and Improved Casting Box, of which the Jfollowing is a description.

My invention relates to stereotyping machines and more. particularly to the casting box thereof for making high type cuts or plates or the like.

The general object of my invention is to provide an improved casting box and a novel form of coacting gage or stop-ott bar whereby to make it possible to produce a type-high cored cast of any size with crossing legs or ribs so that any size cut produced will sta-nd upright and also having bearing surfaces on all sides.

In carrying out my invention I produce the back platen of the mold not only with vertical grooves as is usual but with horizontal crossing grooves and I provide the movable gage or stop-ofiF bar with tongues or teeth that exactly iill the horizontal grooves closing the same against the escape of the metal.

Reference is to be had to the accompanying drawings forming a part of this speciication, it being understood that the drawings are merely illustrative of one. example of the invention.

Figure 1 is a perspective view of a stereotyping outtlt having a casting box and gage bar formed in accordance with my linvention, the view showing the mold in open po sition, that. is to say. with the Jfront .platen brought away from the back platen into horizontal position;

Figure 2 is a side elevation with a portion broken away, the mold being shown closed;

Figure 3 is a. side elevation of my improved gage or stop-oli bar;

Figure 4 is a horizontal section as indicated by the line 4 4, Figure 2;

Figure 5 is a face view of the front platen and a modified arrangement of gages;

Figure 6 is a fragmentary face view of the back platen in modified form;

Figure 7 is a cross section on the line 7-7, Figure 6.

The illustration of my invention shows the same incorporated in a known stereotyping outit. The numeral 10 indicates the frame; 11, the back platen; and 12, the

front platen. Said back platen has vertical grooves 13 as is customary and in addition said platen, 'in accordance with my invention, is formed with crossing horizontal grooves 14.

The numeral 15 indicates an L-shaped gage or bar at two sides of the front platen while the numeral 16 indicates the second gage or stop-ott bar, each gage bar 15, 16 having a handle 17. assemblage 19 is provided to cause parallel movement of bar 16 when shifted ing its handle 17. It will be observed that the gage bars 15, 16 are formed with tongues or teeth 18 spaced to correspond with the grooves 14 and to enter said grooves when the. front platen 12 is closed against the back platen. y

The crossing grooves 13, 14 serve to produce crossing legs or rilos on the cast being made so that any size out will stand upright and present bearing surfaces on all sides.

The numeral 20 indicates a known arrangement of links connecting the front platen 12 with the frame 10 to permit of a movement of said platen 12 from the closed vertical position to an open horizontal position.

To make a cast with the described mold the paper matrix is laid on the liat side of the mold face. up the gage bar or metal retainer 15 is placed over the adjacent edge of the matrix and the bar 16 is placed any desired distance from the bar 15 so that with the closing of the front mold against the back mold the tongues 18 by entering the grooves 14 will close said grooves and prevent escape of the metal at either side. The tongues 18 are made type high from the edges of the tongues to the bases or the flat sides of the bars 15, 16 presented to the matrix. The tongues 18 and the grooves 13, 14 are V-shape.

In Figure 5 the bar 115 corresponding with the bar 15 is L-shaped in plan and it contacts with a plain flat edge portion 21 on the back platen. In Figure 6 there is a gate passage 22 extending partially along one side of the flat edge portion 21 and adapted to receive material from the spout 23 at a side of the casting box 24. It will be understood that the spout in practice may be disposed on the casting box i-n other positions. In the back platen, Figure 1, similarly, is shown a vertical side gate passage 122 for the material received from the cast Any approved link by grasping box, the spout 23 being similar-ly positioned= I Would state in conclusion that While the illustrated example constitutes a practical embodiment of my inventiona do not limit myself strictly to the exact details herein illustrated, since, manifestly, the saine can be considerably varied Without departure from the spirit of the invention as defined in the appended claims.

Having thus described my invention, l claim:

l. A casting box including platens, a pair of gage bars on one platen, means permitting adjustment of one of said bars relative tothe other, said platens constructed to maintain the bars in parallelism.

2. A casting box including platens5 one of which is formed With longitudinal and transverse grooves, a pair of gage bars on the other platen, said gage bars each having tongue-s to enterthe transverse grooves, and equalizng links connected to one bar to maintain it in parallelism With the other bar regardless of its adjustment relative to said bar.
